GARAGE Application filed May 15,

This invention relates to apparatus for dispensing lubricant underpressure.

In places such as assembly plants and garages, where lubricant isinjected under pressure to machinery bearings, it is desirable andcommon practice to provide an apparatus which includes a container oflarge capacity. Usually such apparatus is provided with a single conduitleading therefrom for forming a direct contact with the nipples throughwhich lubricant is injected to the machinery bearings.

An object of my invention is to provide a structure of the abovedescribed type which is constructed to fill the barrel of hand operatedlubricant injecting apparatus, such as are usually furnished withautomobiles and similar machinery.

Another object of my invention is to provide the outlet of a container,from which lubricant is dispensed under pressure, withmechanism forselectively feeding lubricant to a nipple engaging conduit, or to anoutlet adapted to fill the barrel of another lubricant dispensingapparatus.

Another object of my invention resides in providing a rigid holder towhich the outlet conduit and the nipple contact dispensing nozzle areattached.

These and other objects and the invention itself will be more clearlyunderstood from the following detailed specification.-

In the accompanying drawings Fig. 1 is a side elevation of a dispensingapparatus, partially in section, embodying my invention;

Fig. 2 is a top plan view of the same;

Fig. 3 is a medial sectional view of the outlet housing, showing thevalve mechanism in position to direct the lubricant into'a hand operatedlubricating apparatus;

of the axle. A metal supporting member 14 is secured to and depends fromthe opposite side of the frame and medially of the wheels 13. Thesupport Hand the wheels rest upon the ground, or floor, when theapparatus is stationary, and the apparatus is tilted so that the weightis supported onlyon the wheels when transportation is desired. A pair ofhandles 15 are secured to the underframe and project upwardly andoutwardly. The operator can control the transportation of the apparatusby the handles.

The top 16 of the tank is provided with a central aperture 17 andmechanism for conveying lubricant under pressure from the tank into anoutlethousing, extends into the tank through such aperture. A. pumpcasing and conduit consists of a housing 18 which is provided with abase flange 19 adapted to be secured to the top of the tank over theaperture 17, and a cylindrical shell 20 is screwed to the threaded end21 of the housing extending into the aperture. An inlet member. 22 isscrewed into the lower end of the pump shell and is provided with anaperture 23 extending therethrough. A valve 24 is mounted with the inletmember and is adapted to be moved vertically, the normal position of thevalve closing the aperture 23. A piston 25 is reciprocablv mounted inthe shell 20 and is secured to the endof the rod 26. A rack 27 extendsthrough the housing 18 into the shell and is secured to the piston rod.The piston is provided with a vertical aperture 28 which is normallyclosed by a spring pressed valve 29.

A gear 30 is positioned within the housing 18 and mesheswith the teethof the rack 27 to reciprocate the piston, when rotated in oppositedirections by the operator. The gear is secured to the shaft 31extending through a wall of the housing, and an operating lever 32 issecured to the shaft externally of the housing. The down movement of thepiston raises the valve 29 and closes the valve 24, so that lubricant inthe shell will be forced above the piston. Upward movement of the pistoncloses valve 29 and opens valve 24,

drawing a supply of lubricant into the shell from the tank through theinlet member, and compressing the lubricant above the piston.

An outlet pipe 33 is secured to the housing and the operation of thepiston will force lubricant through such pipe under pressure.

The reservoir and pump mechanism described are of a conventional formand my invention has to do with the conveyance of the lubricant from areservoir which I will now describe.

I provide a distributing casing 34 into which the outlet pipe 33 extendsand is in open communication with. The outlet pipe 33 is screwed into aninlet opening 35 in the side wall of the casing and is in opencommunication with the interior thereof. An outlet port 36 is formed inthe bottom wall of the casing and an outlet port 37 is formed in the cap38 which is secured to the top of the casing and forms a part thereof.The ports are in axial alignment and a hollow sleeve 39 extends throughthe ports and is slidably mounted therein through the interior of thecasing. An outlet passage 45 is formed in the lower portion of thechamber in communication with the port 36 and a connection 40 is screwedtherein.

The sleeve 39 is provided with a plurality of apertures 41 through thewall adjacent the lower end, and a plurality of similar apertures 42 areprovided in the wall of thesleeve adj accnt the other end thereof. Apair of pins 43 are secured to the wall of the sleeve within the casingand a coil spring 44 extends around the sleeve intermediate the bottomwall 45 of the casing and the pins, to normally maintain the sleeve inupward extended position.

A nozzle 46 is secured within the end of the sleeve extending throughthe port 37 in the casing and a passage 47 extends axially through thenozzle. The exterior end of the nozzle is circular and thecircumferential edge 48 thereof provides the contact with thelubricating apparatus which is to be filled.

A flexible conduit 49 is secured at one end to the connection 40, and isfastened to a hollow handle 50 at the other end. The end of the conduitfits upon a reduced end 51 of the handle and is secured thereto by ahose clamp 52 of conventional design. The handle terminates at the otherend in an end wall 53 having an aperture 54 therethrough. The threadedstem 55 of a hollow nozzle 56 is screwed into the aperture in the endwall of the handle. An annular shoulder 57 is provided within thepassage 58 extending through the nozzle and a ball valve is positionedwithin the passage. The ball valve 59 is normally held against the innerside of the shoulder by a coil spring 60 which bears against an inwardlyextending flange 61 at the end of the nozzle, being thereby retainedwithin the passage in the nozzle; A contact,

member 62 extends through the outer end of the passage in the nozzle andis slidable lengthwise in the nozzle. A flange 63 is spun inwardly atthe end of the nozzle to limit the reciprocation of the contact member.The end face of the contact member is formed with a semi-sphericalrecess 64 therein and a passage 65 extends axially through the contactmember, being larger in diameter-at the rear of the end face. A gasket66 having a central aperture therethrough bears against the inner end ofthe contact member, within the passage in the nozzle and preventslubricant from escaping between the walls of the contact member and thenozzle. A washer 67 is positioncd against the gasket, and a coil spring68 maintains the washer and gasket in position, the spring bearingagainst the washer and the shoulder 57 which projects into the nozzlepassage. A stem 69 extends through the inner end of the passage in thecontact member into the passage in the nozzle. The stem is seated withinthe contact memher and is arranged to unseat the ball valve 59 when thecontact member moves inwardly of the nozzle.

When the sleeve 39 is in its uppermost position the apertures 42 thereinwill be closed from the interior of the casing, as they extend withinthe walls forming the port 37, and the apertures 41 will lie within theinterior of the casing in communication with the pump casing. The sleeveis provided wlth a partition member 7 0 intermediate the apertures inthe opposite ends thereof, and lubricant'will be free to be forcedthrough the end of the sleeve, the conduit 49, the handle 50 and intothe end of the nozzle passage. When the valve is opened by the stem 69,the lubricant will be ejected through the nozzle and the passage in thecontactmember. It will thus be seen that it is necessary for the contactmember to be moved inwardly to permit the valve 59 to open and allowlubricant to be ejected through the nozzle.

The recessed end face of the contact member is adapted to fit over andagainst a contact face of a bearing nipple similar to that of the nozzle46 to provide a leakpr oof contact therewith, which is manuallymaintained in a plurality of angular relations thereto. A nipple andcontact member of this nature are shown in Patent 1,475,980, issuedDecember 4,1923. J

The reservoir can be wheeled about, and can be replenished withlubricant through an opening in the top of the tank, over which a coverplate is removably secured. I have described how the lubricant will beforced from the reservoir tank through the flexible conduit to injectlubricant into bearing nipples, and in Fig. 3, I illustrate the sleevein position to conduct lubricant from the reser* voir tank into alubricating apparatus which is of a size furnished as equipment with anautomobile. When the sleeve is in its lowermost position the apertures41 are covered by the wall forming the port 36 and the apertures 42 liewithin the casing so that communi ation is established between the pumpcasing and the end of the nozzle 46, whereby lubricant can be forcedtherefrom.

In my co-pending application filed on an even date herewith, I haveillustrated a lubricating apparatus, wherein the container can be filledwithout disassembling the parts thereof and in which a passage extendsthrough the handle and the piston rod beneath the piston carried withinthe container. The inlet end of the handle of such an apparatus is shownherein and reference may be had to my other application, above referredto for further details of such an apparatus.

In Fig. 3, 77 illustrates the end of the handle ot' a lubricatingapparatus having a passage 78 extending through the end thereof, and aninlet member 79 is screwed into the end of the passage. A passage 80extends axially through the inlet member and is normally closed at itsinner end by a spring pressed ball valve 81. The pressure of thelubricant will urseat the valve when being forced through the inletmember and when there is no pressure the valve will seat to'preventlubricant from escaping from the handle. The end face of the inletmember is formed with a semi-spherical recess 82 which is of suflicientarea to re eive the circular peripheral edge 48 of the nozzle therein.By placing the recessed face of the inlet member in the handle againstthe nozzle 46 and exerting pressure thereagainst, a leak-proof contactwill be mat e and the sleeve. w ll be pressed inwardly establishingCOIIIIDIUIICHtlLJI between the upper end of the sleeve and thereservoir. lVhen such contact is made the operator reciprocates thepiston forcing lubricant through the handle of the lubricating apparatusto be filled. Thecontact of the faces of the nozzle and inlet member aresuch that a leak-proof connection can be formed when the handle is heldat various angles relative to the nozzle, as long as the passagestherein remain covered.

The casing and sleeve will thus provide two outlets, one for filling alubricating apparatus and the other for directly connecting with bearingnipples, either one of which can be placed in operative relation bydirect manually maintained contact.

A bracket 83 is secured to the top of the pump casing to receive andmaintain the handle of the conduit when not in use. A metal band 84 issecured around the tank and spring clips 85 are secured thereto andserve as retainers for lubricating apparatus, of the type which arefilled from the nozzle 46.

Various changes can be made in the construction described withoutdeparting from the spirit of my invention and the scope of the claims.
